Free span 4m length and strong enough to take the weight of 2 tradesmen

This project was finished recently and hopefully this will help you understand the benefits of our system more.

You will be able to see, how quick the installation process is with our 74mm polycarbonate system, and how construction time is dramatically reduced. Installation time on this project was a full day from start to finish. The steel purlins were already erected and in place.

Everbright E610 Opal was installed above two court yards over several commercial offices, and residential units. Everbright E610 was supplied curved, incorporating Locking System 1 (see design loads).


The brief given was for a modern curved roof, that could free span the required distance without any intermediate supports. The Idea was to give a seamless and continuous line, with no steel frame work spoiling the visual effect. E610 Integral locking bars hide the aspect of where a panel starts and where it finishes, so it becomes a continuous system giving a uniformed and conformed design feature. Creating an architectural flare, that isn't possible with any other polycarbonate system available on the market. Since less structure is required, less shadows are created, and as such the natural light translucency is at it's full potential.

On this project E610 was pre curved, and in one complete 4mtr length. Our panels are also supplied in 600mm configuration, and simply clip together. Making the installation process very rapid, as our product only requires to be joined every 600mm on site.



As you can see from the photographs, E610 is an extremely light weight product, and can be easily manoeuvred during the installation process. Our 74mm polycarbonate panels are also fully trafficable, which makes a huge difference to construction time, and helps with general service and maintenance of the roof.


This project consisted of two roofs, both areas measured 4mtr span/projection x 24mtr wide.
The geometry details on this project were:
Internal Radius 2.8 mtr
Springing Angle 37.59 degree
Mid point height 581 mm

Free spanning commercial gable 4m
